Scott Drake upholstery sets are the best on the market, precision made from the same heavy duty vinyl and attention to detail originally used by the factory. Custom colors are an exact match. Heavy 32 ounce vinyl and solid welt cord. Patterns are die cut for precision. In the case of Pony/Deluxe/Mach 1 patterns, they have the same detail as the originals. Kits do not include hog rings for installation.
